Main features

1, The direct-coupled design is easy installation and can save space.
2, The bearings are all the Japanese NSK.
3, The standard configuration uses the John Crane mechanical seal which can eliminate leakage and easy to maintain.
4,The pump has the cavitation protection port, when it works under the ultimate pressure, the cavitation protection port opens (or connects with the separator) in the case of ensure maximum suction effect to eliminate the noise of cavitation and protect the pump

5,2BV whole series are all use the aluminum bronze impeller with high strength and raise its corrosion resistance and durability. If the liquid flows parts adopt stainless steel, the pump can work in the more hard condition.
